Abstract
본 발명은 원심펌프에 있어서, 날개가 있는 디퓨저에 대한 콜렉터에 관한것이며, 콜렉터 배출도관 입구에서 콜렉터 하우징의 방사상 단면적은 배출도관 입구면적의 40내지 80퍼센트이며, 배출도관 입구까지 유연하게 진행된다. 콜렉터 하우징에 있어서 단면적의 진행은 콜렉터 축방향 높이의 변화에 의해서 제공된다. 배출도관과 함께 이루는 교차점에서, 콜렉터는 축방향 높이로 단을 가지며, 이에 따라 유동이 콜렉터로 부터 배출도관 입구까지 적어도 부분적으로 원주방향을 향하게 된다.The present invention relates to a collector for a winged diffuser in a centrifugal pump, wherein the radial cross-sectional area of the collector housing at the collector outlet conduit inlet is 40 to 80 percent of the outlet conduit inlet area and proceeds flexibly to the outlet conduit inlet. Progression of the cross-sectional area in the collector housing is provided by a change in the collector axial height. At the intersection with the exhaust conduit, the collector has a stage at an axial height such that the flow is at least partially circumferentially from the collector to the outlet conduit inlet.
